Re: 6/26/84 Pitch Problem
This link offers some interesting technical discussion about pitch correction and speed errors on old tapes. Readers may glean information on how to:http://www.archive.org/post/296074/are-these-tapes-in-tune
a) Perform non-destructive
tempo, pitch, or speed shifting yourself. Do these separately, or all at the same time, using freeware software. The download link to PaceMaker
b) Perform destructive
pitch correction using Samplitude Pro
c) Understand and perform the math to do pitch correction vs speed correction vs beats per minute (BPM). Or, decide to use the Resampling mode.
Since I originally posted the above discussion, Magix AG company has ported their Dehisser and their Resampling (pitch correction) modules - from their Samplitude Pro s/w products - into a new s/w product named Audio Cleaning Lab
. We can further enhance this discussion by reading the thread that describes this new s/w product adventure by Magix.http://www.archive.org/post/318238/free-audio-restoration-software
Most importantly: pitch correction fixes requires someone with perfect pitch to analyze the original recordings, determine the error factors first, and then get them quantified exactly correctly. I cannot do this since I am not musically trained, and I do not know anything about perfect pitch.
I respect Charlie for using this procedure. Mistakes will happen. I have made several mistakes with fixing tapes. Thanks again for doing your work, Charlie, and sharing these tapes with the rest of us.
I have successfully learned how to do much of this myself, having watched Charlie and others doing it. It takes a long time to get good at this.
